ERROR: The OpenGL functionality tests failed!
You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL[_ES2],
QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform.

while checking the config.log file,i understood in my sysroot ,I dont have the libegl packages,how to install those packages? please guide me....

in my qmake.conf file
QMAKE_INCDIR_EGL=
QMAKE_LIBDIR_EGL=

this both are empty...what i need to specify there...below is the attachement of my qmake.conf file please go throught that one.....

@Asha You can't execute *.o files!
Those needs to be linked together to an executable.

"arm-linux-gnueabihf-g++: error : .o - please delete everything in your build directory, run qmake again and then build (call make).
Also this error message looks strange - there should be actual file name in front of .o

You just need to build again!
"I am not getting any executable file" - yes, because your build fails.
Before I wrote: please delete everything in your build directory, run qmake again and then build (call make).
So again: please run qmake and build.
